This afternoon, the Associated Press is reporting that United States officials have officially ordered all public health officers to cease working at the World Health Organization just days after President Donald Trump signed an executive order pulling the United States out of the World Health Organization.

As part of a rash of executive orders completed on his first day back in the White House, President Donald Trump began the nation’s exit from the World Health Organization. Here, we explain how the withdrawal would work and what it would mean,

As of President Donald Trump’s first day back in office Monday, the United States is leaving the World Health Organization. Some local experts think such a move might leave Spokane and the United States unprepared for the next pandemic.

The World Health Organization is shaped by its members: 194 countries that set health priorities and make agreements about how to share critical data, treatments, and vaccines during international emergencies.

WHO’s constitution, drafted in New York, doesn’t have a clear exit method for member states. A joint resolution by Congress in 1948 outlined that the U.S. can withdraw with one year's notice. This is contingent, however, on ensuring that its financial obligations to WHO “shall be met in full for the organization’s current fiscal year.”

Public health experts say the United States’ departure could cripple the WHO’s operations or leave an opening for China to assume greater control over the agency.
